. One ofthe principal objects of the present invention is to improve the window constructi'on ofthis copending application.

Another-object is to produce a window of this general type havinggreater strength than prior windows of this class while still maintaining the relatively narrow frame and sash which is of advantage in admitting a great-er amount of light for the size of the window opening.

Another object is to reinforce the inset window along the center thereof.

Another object is the provision proved latching mechanism. 7

Another object is to improve the frame structure in which the inset window is hinged;

Another object is'to improve the hinge structure. z 7 7 Another object is to provide a fastening of an immechanism for holding the inset window in a partially opened position.

Another object is to provide a window of this type which may be formed up entirely ofv sheet metal.

Another object is to provide an internal base for a. narrow section of sash so ,that'the wall of thesashmay be formed of relatively thincross section. I

channels .on the sides thereof intowhich' the glass panes of the large w-indowxa-re glazed? The pane of :the inset window is clamped all around the edge thereof by the inset window sash, the usual glazers cement alsoheingieinployed, and thezsash being pivoted to the inset frameso' as to swing througha full degree are and lie against the inside face of the :main window. i

v I may form window of various mate rials depending upon the particular results desired, and the conditions encountered but in general I'prefer to employ for-one type eitherzaluminu-m or a light: aluminumalloy,

and for .anothertype Isecurewthe best results I by the use of steel. In the drawings Figs. 1 to 7 inclusive show a design which I prefer to make use of when the material employed is aluminum or a light aluminum alloy; while Figs. 8 to 13 inclusive show a design making use of formed sheet steel. These two designs have many features'in common and while best suited for the materials for which they are designed, may without difficulty be produced from other materials. NVhere therefore in the following description reference is made to the materials from which a window is produced, these materials need not necessarily be used, the scope of the invention beingdesignated by the claims.

' Referring now to the first form of the invention the inset window is adapted to be used with any species of large window, but it is shown with a window of standard double hung check rail type, the sash of the main window comprising a check rail 10, uprights 11 and 12 and bottom rail 13. The usual large pane of glass 14 is held in the sash of the main window but has a center portion thereof removed for receiving the inset window frame. The inset window is of the casement type and is hinged to the inset window frame and swings inwardly in a manner and for the purpose described.

The outer frame comprises an upper frame member 16, lower frame member 17 and sidemembers 1818. The top, bottom and side membersare all differently formed but each is so arranged thatithe casement window may be fitted snugly thereagainst when the in set casement is closed.

The top framermember comprises a main horizontal web 16a thickened at 16?) to'form a better engagement with the easement, and is provided with a downwardly projecting flange 160 against which the top of the casement frame is held when closed. An upwardly extending flange 16d is fitted into the usual groove in the'check rail and a screw or nail 19 extending through suitably provided apertures in the web 16a facilitates holding the upper frame member in position. The .flange 16d is narrower than the slot or groove in the check rail, being about the same thickness as the window pane with which it is in alignment. The usual putty or cement'21 is employed in the groove and may be placed therein at the same time that the panes are glazed in the main window.

The bottom frame member is of general U shape with a bottom horizontal portion 170 and upstanding sides 17b and 170, the side 170 being on the outside and serving as a stop for the easement and against which the casement is held in firm contact when in closed position. A thickened bevel flange 17d projects inwardly from. the upright portion 176 and serves to engage the'bottom of thecasement. The bevel or slanting character of this flange serves toovercome any possible sagging of the easement by raising the easement upon the slanted surface as it is closed. The bottom frame member is wide enough at its lowest part so as to cover the entire putty space, attachment to the bottom rail being secured by nails or screws 22 driven through suitably provided holes in the bottom frame member and imbedded in the wood of the bottom rail. The usual weep holes 23 are formed to tap the well-like opening in the bottom frame member in order to drain any liquid such as condensate which may become lodged therein.

The side or vertical frame members are the same on each side with the exception of course that their positions are reversed. The cross sectional shape of these side members is shown in Figs. 8, 4; and 6. The members comprise a main web 18a, thickened at 186, with outwardly extending flanges 18c and 1803 giving riseto a channel therebetween, and an outside inwardly projecting flange 186 against which the inset casement bears when in closed position. The channel between the flanges 180 and 1862 is to accommodate the glass pane of the larger window, this pane ext-ending thereinto and held against the larger of the two flanges, cement 24 being employed to hold the glass in position.

Any suitable means may be resorted to for holding the four frame members together. I have obtained results most satisfactory to me, by mitering the corners and welding them together. This makes a substantially uni-piece frame and results in a more satisfactory job for most purposes.

The casement or sash is formed of four sides, namely the top 26, bottom 27 and two uprights 28-28 mitered and held together at the corners, suitably glazed and hinged to the inset frame. Each one of these members has the same cross sectional shape, and in order to make clear the arrangement and purpose thereof, reference will be made to the up per member 26 only. This member is of general U shape having a main web 26a with the portions 26?; and 260 forming the sides of the U, and right angular flange projections 26d and 266 from the side U portions. The U shape character of the member'gives rise to a relatively large channel, and the flange projection 26d projecting over the channel results in the production of a closed channel area 26/ which is so arranged that the glass pane 29 cannot be extended thereinto. When the. glass pane 29 is in place it lies against the edge of the flange 26d and so closes off the area 26 as to completely separate it from the other portions of the channel. Cement 31 is employed to fill the balance of the channel after the pane 29 is in place.

Where an unusual strain is applied to any of the frame members I may modify the thickness of the walls to secure greater greener:

strength, or as I prefer to do in most instances- I may employ a reintorcing-insert3O which will positively prevent all torsional strain on the" sash frame, as well. as considerably augmenting its strength in bearing ordinary bending stress. I have found that the greatest strain-is in thememher to which-the hinges I are secured, and I accordingly show the insert employed within this member, It is shown havinga formed shape to facilitate anchoring it in place but it may take any shape desired which will have a satisfactory reinforcing elie'ct. Theshape of insert shown (vide Fig. 3) has the advantage-of permitting the glass to be extended farther into the sash 1 be described in connection therewith.

"The hinges comprise "two hinge plates 32 and 83Ywith the 'usual formof hinge pin '34 securing them together. The hinge plate 32 is secured to-the side 28 of the casement by means of rivets 36-36, one short rivet extending through the web 28a and flange 28d, as well as through an angle insert 37Wl1lCl1 is square in cross section andfits into theclosed channel area 28 (Fig. 5). Then to secure.

in position the side 28 bearing't he hinges, the opposite leg of the angular in'sert37 is extended into the closed area 26f -ot the top:

casement member and secured therein by machine screws Sid-S8 extending throughthe web 26a. These machine screws are countersunk so as to interfere in no waywh'atsoever with the operation of the window, and at the same time the heads thereof are normally concealed from view. A rivet 36a is also secured through the member 28 andthe angular insert 37, withoutfhaving any connection whatsoever with the hinge. 3

In hanging-the casement or sash ofthe inset Window, the hinge plates 33- are secured by means of machine screws 39- 39 to the uprights 18, Preparatory to securing the hinges in place, however, a slot iscut in the thickened portion 18b of the web as Wide as the hinge plate-but double the thickness thereof, so thatthis slot is j-adapted to hold both hinge plates when the window is closed and accordingly the hinge plate 32' is secured directlyonto the sash member without pre par-ing it in any way with the exception of course of drilling the usual rivet holes therein. v v I 1 In securing the hinges in place, the plates may be secured with substantially'their whole area in contact with the members to which they are secured as shown the present case or the hinge may proj ect considerably beyond the two upright members so that the hingepin is, say-a half an inch, an inch or even more away irom the upright members This is a more'or lessordinary modification in the use of hinges but inasmuch as I have shown the prior arrangement, I 'wishto bring out the fact that the hinges'may be arranged so that if-there isany object to be cleared when the inset casement lies back inextre'me open posi tion, the necessary changes in the hinges may be made.

WhileIinay employ many different kinds of latching mechanisms with my invention, still all of the conventional arrangements with which I am familiar are disadvantageous in some respect or other, accordingly, I. have" provided a novel arrangement making use of the peculiar arrangement of the sash and irame and functioning very satisfactorily in this particularposition.

A latching rod 41 (Figs. 3 and 6) is providedsto fit snugly into the closed area 287' and having right angular projections 41a at both the top andbottom thereof extending through elongated slots 42 in the web 28a.

The portion 28b of the upright casement member has a slot 48 through which a connection is made to a plate 44 by means of screws 46 extending through the plate and into the latching bar. A handle 47 is also 1 provided on the plate 44, this handle 47 being secured thereto by a screw 48 threaded through the hollow interior of the handle and having a relatively large head which bears against the latching rod 41 so that when the screws 46 are pulled up tightly, the cover plate 44' is held securely to the latching rod 41 but at the same timesuch plate hasno tendency to bind against the face of the flange. An angular insert 49 of sheet "metal or similar thin material isprovided to avoid the possibility of the cement 31 coming in contact with the latching rod and cramping its action. In order to form an engagement with the projectingends 41a, of the latching rod, cam slots '51' are provided in the thickened portion 1879 of the web, so that as the window is closed, the projections 451a extendinto the cam. slotdirectly, and downward pressure of {the handle 47 draws the latching rod 41 downwardly and causes the projections 41a to .ride along the cam slot-and force the entire casement or sash outwardly,

so that the portions, 260, 27c and 280 bear against the stop flanges on the inset window frame. V p

The inset window-of my lnventionhas very narrow frame and sash members so that only a limited amount of light .is cut out thereby;

nevertheless, exceptional strength is obta'ine'd'by the particular arrangement employed, which :is 'suflicient for all ordinary ice installations. However, if an exceptional long inset window is employed a s'indicated,

I may provide astrengthening Inuntin across the center of the easement, or as a matter of fact such a muntin may be employed for decorative purposes. only and constituting part of a general decorativescheme. Independent of what the muntin is, the arrangement illustrated in Figs. 1, 2 and 7 may be employed. In this arrangement, the muntin comprises a pair of parallel webs 53 and 54, one slightly wider than the other, and connected at their centers with a continu ous intermediate web 56 so that a member of substantialy I-shape cross section is obtained. To prepare themuntin for mounting in position, portions of the webs 53 and 54 are cut off the end thereof so as to result in end projections 56a which extend into thev channels in the side casement members 28, the muntin being secured in position by machine screws through the web of the members 28 and eX tending into threaded screw holes in the end projections56a. The glass pane is glazed in the channels between the flanges 53 and 54 as shown in Fig. 2. 7

An inset window of this type is of advantage to permit washing the window without going to the outside thereof and. also to fa cilitate ventilating. WVhen used for cleaning or repair purposes, the easement is swung through a full 180 degree are so as to lie flat against the inside of the main window. When employed as a ventilator, however, it is desirable at times to have the window only partially open and for this reason I provide a holding mechanism so that the window may be secured in various partly open positions.

One form of fastener with which I have obtained good results comprisesa single rod 57 of springmaterial having an upturned projection 58 extending through the check rail and held in place by a nut 59, and a shorter downward projection 61 at the other end of the rod adapted to lit into any one of a plurality of apertures 62 and the web 26a of the top casement window. The apertures 62 are connected by a groove 63 which is of ad vantage in facilitating insertion into the apertures. As illustrated in Fig. 2, the portion of the rod 58 is-secured in the check rail at a slight angle so that when the rod extends out away from the check rail in the position inv whichv itengages in the apertures 62, it extends partly downwardly, thereby serving to hold the downward projection 61 firmly in position- When the window is closed,

' however, and the rod 57 swung back against 51 on one side and the slots on the other side for receiving the hinges. The four sides of the frame are then welded together at the. corners and this completes the manufacture of the frame.

In the manufacture of the easement or sash side bearing the latching rod, it is first provided with the slots 42 and the slot 43. The

latching rod 41 is then slipped into the closed channel area 28; with the projections 41a extending through the slots 42. The plate 44 with the handle 47 secured to it, is then placed over the slot 43 and the screws 46 employed to fasten the plate to the rod, suitable screw holes having been provided previously therein. The other side member of the easement is then prepared, the angular inserts 37 being secured in the area 28f of this side by the rivets 36a. The hinge plate 32 has previously been secured in position by a smaller rivet or screw and the long rivets 36 'are then placed in position extending through two portions of the side member and through the hinge plate. The top and bottom and the side member containing the latching red are then welded together making a three sided figure, the glass pane slid sideways into its channel, and the side bearing the hinges then secured in position. This is done by simply extending the free legs of the angular inserts 37 into the closed channel area of the top and bottom members and screws 38 then employed to complete the assembly. The usual glazers cement is of course used to complete the job.

lVhen assembling the complete inset window into a large window, the frame is glazed into the large window in the same way that the glass panes 14 are. As a matter of fact, I prefer to secure all of them in positionat the same time. The inset casement may of course be secured in its frame before the frame is mountedin the window; but if not it is secured in position by the simple expedient of applying the screws 39.

The form of invention shown in Figs. 10 to 13 inclusive is particularly adapted to be produced from sheet metal, preferably sheet steel which is either in itself rust proof, or which is treated by a coating or the like to make it rust or weather proof. The principal purpose in connection with the manufacture of the window formed from sheet metal is to produce a stronger structure, with the frame all the narrower so as to offer less obstruction to the light, and probably most important of all to reduce the cost of manufacture. This and other objects are accomplished by the design of the members which I show in the drawings now under consideration.

In the description of the second form of the invention I shall as far as possible employ reference characters identical with those employed in connection with the first embodiama ment wi h he exceptio the prefixing of a digit 1:. For example where a referencecharacter is employed in the first form the memberin the, second form of the in,- vention corresponding with the member 10 in the first form of'the invention will bear the reference character 110. This is for the convenience ofthose skilled in the art in arriving at a-clearerunderstanding of the inventiom and is not intendedto limit or introduce any matter in derogation ofthe scope ofany of the features, a

y The inset window of this form is also adaptedfor use with a standard window of the double hung check rail type, the sash of the main window comprising a check rail 110, uprights 111 and 112 and a bottom rail 113 the usuallarge pane of glass 11 1: being supported by these members. v-

The outer frame comprises an; upper-frame member 116, lowerframe member 117 and side frame members 118- 118 In this'form of the invention the top,bottomand side members are all of the same crosssection, a form 5 being utilized which will not onlyv receive the large windowwhen these members are.

used as side members, but with substantially equal facility may be secured to the check rail and bottom rail of the main window. For this reason as far as an understanding of the shape of this member is concerned a description of the side memberfswill suflice.

The side and vertical frame members of the inset frame are mounted in identical positions with the exceptionthat they are reversed. The members comprise a main web 118a taken at 11872 with outwardly extending fianges118c-and 118d giving rise to a channel therebetween with an outside inwardly aeprojecting flange 118@ against which the inset casement bears when in cross position.

This member is formed entirely of sheet steel, the outer projection 1180Vbeing formed by bending the material from theweb outwardly and then doubling back upon itself to form a wide outer flange; and a relatively thin insideor stop.flange. f The thickwing at 118bisalso produced by employing adouble thickness, but in this respect the 50. shape is somewhat different than in the alum inum form. The thickening is on the outside instead of on the inside of the'flange, and

,a separate inside projection 118) is formed by bending the Web at. right angles toward which appear obvious. v The material isthen bent around the corner to extend partly the width of the web and then at right angles again away from the web reform the out- -;wardly extending flange 11 8b. f e As the drawing shows the frame has the 5 same Cross sect on l t e way around a In as w t the aluminum fo m.

tion. This reinforcing strip may be simply slid loosely into position, or to increase its Strengthening effect it may be secured in place. This is done preferably by spot welding the portions 130a and 1267) together, and the portions 130?; and 126a together." Two or three spot welds are suflicient, but more may be employed depending upon the length of'the members secured.

Besides the advantage of being able to secure the reinforcing or strengthening strip in place when this form is employed, it is also found that slightly greater space is provided for the glass than when a straight strip 130 is used as shown in the modified form of Fig. 14. This modified form, however, may possess certain advantages which will make it advisable to use it with certain types of installation.

The hinge arrangement in this form I preferto simplify by spot welding hinge plates 132 and 133 to the outside surfaces .of the easement frame and inset frame respectively, any usual form of hinge pane 134 being provided. In this way the hinges form a substantially permanent part of the frame structure, but the hinge pane may be removed readily without separating the casement for repair or the like. c I

In producing the finished structure of the casement frame themembers 126, 127 and 128 are cut and mitered at the corners, being secured together by welding and by the insertion of angle inserts 137 which in the present form I prefer to make wide enough to extend clear across the inside channel as the drawings illustrate. To do this, however, the reinforcing strip 130 is held at the end of the angle insert, this arrangement being shown in Fig. 12. The angle inserts are spot welded to the casement frame members, the point at which welding, takes place being indicated by the reference characters 136. To facilitate glazing, however, the angle inserts connected to the hinge carrying upright 128 are connected to the casement frame members 126 and 127 by machine screws 128. This construction results in the production of an integral three sided frame, with the third side having the angle inserts welded at one leg thereto. In glazing the glass is slid into position in the three sided frame, after which the fourth side is attached by extending the free legs of the angle inserts into the inner channels of the members 126 and 127 and then attaching the screws 128.

The latching mechanism employed is sub stantially the same, a latching rod 141 being operable through slots 14:2 in the'web. The portion 1286 of the casement is slotted to permit aconnection from a handle 147 to the rod 141 so that said rod may be reciprocable mechanism. The inturned portion 150 also functions to assist in opening the window, as when the end141a strikes against this inturned portion a camming action takes place in the opposite direction and tends to pull the casement outwardly.

In this form I show also a slightly different fastening rod 157, but it is arranged to accomplish substantially the same result as the previously describedfastener. It is formed of spring material and has a bifurcated or forked end 161 which isadapted to engage over the top of the easement. The member 157 being formed of spring material and having its upward projection 158 secured in the check rail at an angle, the bifurcated end will extend on both sides of the casement with a spring tension. The angle of the pivot 158 causes a tighter engagement of the casement the farther open the window is, so that the wind blowing against the window cannot cause the fastener to loosen. This angle also permits the fastening rod to be nection with the aluminum frame window.

In actual use I have obtainedgood results with both of these forms, but conditions may suggest the combination of certain of the features in the two forms,or slight changes therein. The muntin for example may be employed with the sheet steel type of frame and any of the other features may also be interchanged. As already pointed out the selection of materials is in general illustrative, but there are certain features in connection with the use of sheet steel which I consider novel and which require considerable thought and development before this material could be applied to the use of this type of window. For these reasons I do not wish to restrict myself to any of the features, materials or the like above set out, the invention being limited only by the scope of the appended claims.

What I claim as new and desire to secure by United States Letters Patent is:
